Viking(光颉)ARG02BTC1103是一款高精度镍铬薄膜固定电阻,针对对阻值精度、温度稳定性要求严苛的小型化电子系统设计。其以0402超小封装兼顾高性能与高密度集成,适配消费电子、工业控制、通信及医疗等领域的精密电路需求,是替代普通碳膜/厚膜电阻的高可靠性选择。
该电阻标称阻值为110kΩ(标识代码“1103”,对应110×10³Ω),精度达**±0.1%**,满足精密测量、信号调理等场景对阻值一致性的要求——例如在模拟量采集电路中,可避免因阻值偏差导致的采样误差,提升系统输出准确性。
额定功率为62.5mW(0.0625W),工作电压上限50V,在0402小封装下实现了合理的功率密度平衡。该参数可支撑低功耗电路的连续工作,且电压额定值覆盖大部分信号级电路的工作范围,无需过度降额使用。
温度系数为**±25ppm/℃**,属于薄膜电阻的高性能水平,远优于碳膜电阻(通常±200ppm/℃以上)。在-55℃~+155℃的宽温范围内,阻值变化极小:以110kΩ为例,125℃环境下的阻值偏差仅约±2.75Ω,远低于精度允许的±110Ω,确保极端温度下的性能稳定。
采用英制0402封装(公制1005,尺寸1.0mm×0.5mm),是当前电子设备轻薄化的主流封装之一,可有效缩小PCB面积,提升系统集成度,适配智能手机、可穿戴设备等高密度布局需求。
基于镍铬(NiCr)薄膜溅射工艺制备,相比厚膜电阻更薄、阻值分布更均匀,实现了高精度、低温漂与低噪声(噪声系数<1μV/V/Hz),适合信号调理、音频放大等对噪声敏感的电路。
终端采用镀锡/镀镍处理,符合RoHS无铅环保标准,且适配回流焊、波峰焊等常规SMT工艺,生产良率高,可降低批量生产的成本损耗。
智能手机/平板电脑的传感器信号调理(压力、加速度传感器偏置电阻)、音频电路精密分压网络,利用0402封装的小型化优势,适配设备轻薄化设计。
PLC模拟量输入输出模块、温度控制系统采样电阻,宽温范围(-55~+155℃)满足工业现场的极端环境需求,高稳定性确保长期运行无偏差。
基站射频前端信号衰减网络、光纤收发器偏置电路,低噪声特性提升信号传输质量,高可靠性支撑通信设备的7×24小时运行。
便携式血糖监测仪、心电图仪的信号放大电路,±0.1%精度确保测量准确性,符合医疗设备对精度与可靠性的严格要求。
该产品凭借高精度、宽温稳、小封装的核心优势,成为精密电子系统中平衡性能与成本的优选方案。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
